Question: A uniform bar of mass m and length √2R slides inside a smooth circular surface of radius R (Fig.). Use Newton's second law to derive the equation of motion for arbitrarily large angles 9 and determine the forces exerted by the surface on the bar.
water at a rate of 45500 kghr is heated from 80 c to 150c in a shell-and-tube heat exchanger haveing two passes and
the automobile shown has 1200kg mass with center of gravity at point g and all wheel have the same 0.34m radius if the
Oil flows at a rate of 12gpm from a vented tank (pressure at point 1 is zero) through 1 inch inner diameter pipes and elbows, and through a pump and motor as shown. The pump adds HHPp= 3hp to and the motor extracts HHPm= 1hp from the fluid power.
